GSMGB Fringe Areas- Governance Model Options
3/15/2017
Method of participation through MOA to mitigate three main areas of concern with having another jurisdiction exercise authority over groundwater resources 1) influence over potential
limitations on groundwater extractions 2)influence over General Plan Amendments through determination of water resource impacts 3) influence over limitations of fees and charges

Recommended b/c SGMA grants GSAs substantial additonal powers and authorities to ensure sustainable ground water management. City can assume role and access over our jurisdictional
area and potentially grant funding or other opportunities that may be ultimately available through the GSA.

1. Potential limitations on groundwater extractions that the GSA could enforce should groundwater management protection measures dictate. Without having a “seat at the table” through
an independent GSA, these extraction limitations could be enforced without City participation. The City has water rights to one of the private wells located within the basin boundary.
GSA FORMATION CONSIDERATIONS:

2. All future General Plan Amendment changes would require a determination of an adequate water supply by the GSA. SGMA specifically addresses the fact that it does not impact a City’s
land use authority, however any adverse reports provided by the GSA would need to be addressed through the CEQA process.
GSA FORMATION CONSIDERATIONS:

3. GSAs will have the authority to impose fees on groundwater extractions. GSAs will also have the ability to levy and collect taxes, assessments and charges as already provided by
law. Without a separate GSA, the City may have limited control over limiting or impacting fees and charges to Arroyo Grande property owners affected by SGMA.
NOTE: Currently revised County policy would not charge “non-represented” areas.
